Here’s an excerpt from that article: The 2013 numbers led to restrictions on subsistence fishing, and opportunities this year could be even more limited. About half of the run come from Canada, and an international treaty requires that a minimum of 42,500 kings reach the border, Schmidt said.

Restrictions last year resulted in the lowest Alaska subsistence harvest on record, but biologists estimated that only 30,500 fish reached Canada, the fifth time in seven years that the total has fallen short of treaty obligations.
